You can put this solution on YOUR website!
If you have two similar solids, one a larger version of the other, and the ratio of the corresponding lengths is \"x\", the ratio of corresponding areas is \"x%2Ax=x%5E2\", and the ratio of corresponding volumes is \"x%2Ax%2Ax=x%5E3\".
\n" ); document.write( "So the answer is \"2%5E3=2%2A2%2A2=8\".
\n" ); document.write( "This is how the large cube would look if you made it out of the smaller cubes.
\n" ); document.write( "You would have 8 small cubes: two layers of 4 cubes, one on top of the other,
\n" ); document.write( "Each edge of the large cube is 2 times as long as the edge of a small cube.
\n" ); document.write( "Each face of the large cube has 4 times the area of the face of a small cube.
\n" ); document.write( "The large cube has 8 times the volume of a small cube.
\n" ); document.write( "
\n" );
